Now there's a new way to fix a damaged cill

Each Cover Trim is supplied in a standard AC225 depth, but handy 'v' shaped notches indicate exactly where it can be trimmed down to fit AC125, AC150 or AC180 cills.

Then, it's just a matter of cutting away any splinters or damage, cleaning the existing cill surface and gluing the Cill Repair Cover Trim over the top. Simple. And once sealed, it's as strong, permanent and weatherproof as the original.
